Let us know if a new one makes any difference. Mine also has a lot of play but didn't seem to cause any operational problems.

Kevin,

Just checking back in. Thanks for your reply. Since replacing most of the sensors, I was able to get my boat back into the water this summer with no issues. The website looks great!

Which sensors would those be? My 2000 240 EFI randomly shuts off but can be restarted and runs fine until it shuts off again. Some days it will run without incident, some days it will shut off several times.

thanks, jeff

Mine did this last summer. It would shut off at full speed like someone pulled the lanyard, but then start right back up just fine. I changed the plugs and the fuel filter and it still had the same issue. After reading the engine specs Kevin sent me, I noticed there is a second small inline fuel filter. I changed it and have not had this issue since.

Hope this helps,

Exact same problem I have been having on my 2000 M2 240EFI, intermittent shutoff, but starts right back up. Seems to be very common as I have seen this on several forums. I have done all the filters, spark plugs, exhaust hoses, fuel treatment, etc. It does not do it enough to be a major concern, but enough to be annoying. Sure would be nice to figure it out. I'll have to keep searching for other ideas.

Going out tomorrow, so I may try the Seafoam treatment that you mentioned. I also need to look into the CPS, but I seem to recall that my model, year 2000 does not have one.

Any other ideas or a list of possible things that cause this engine to randomly shut off appreciated.
